How it works
When two restaurants, three films or five holiday ideas are all equally fine, stop arguing and draw one. Every option has the same chance, so the answer is as fair as it is arbitrary.
The formula
Pick one option uniformly from the list: each has a 1/n chance.Random Choice Generator: common questions
